Recently, high temperatures gases are used to make gas turbines more effective. Ceramic spraying is an effective technique used to protect component material against the attack of such gases. However, cracks and delimitation can occur in the ceramic coat because of a difference in mechanical property. These cracks and delimitation become a serious problem since they reduced the strength of material. In our research we conducted a fatigue test at high temperature to find the best thermal spraying conditions.
